| # ASR CYGNSS-SMAP H-GMM reproducibility repository |
|
|
| This public dataset repository stores **derived CYGNSS-SMAP collocations, model |
| checkpoints, evaluation statistics, and manuscript figures** for the manuscript |
| on year-adaptive CYGNSS sea-surface wind retrieval. |
|
|
| ## Upstream public data |
|
|
| - CYGNSS Level-2 Science Data Record v3.2 (`CYGNSS_L2_V3.2`), NASA PO.DAAC, |
| DOI: 10.5067/CYGNS-L2X32. |
| - JPL SMAP Level-2B CAP Sea Surface Salinity and extreme-wind product v5.0 |
| (`SMAP_JPL_L2B_SSS_CAP_V5`), NASA PO.DAAC, DOI: 10.5067/SMP50-2TOCS. |
|
|
| The upstream raw HDF5/netCDF granules are **not mirrored** here. They are |
| retrieved temporarily in Google Colab, transformed into quality-controlled |
| collocation shards, and deleted after the derived shard has been uploaded. |
|
|
| ## Repository structure |
|
|
| - `data/collocations/`: monthly Parquet shards for 2021-2025. |
| - `training/`: balanced historical training sample. |
| - `models/`: hard-gated H-GMM and chronological calibrators. |
| - `predictions/`: 2025 raw and strict out-of-time test predictions. |
| - `metrics/`: JSON/CSV statistical outputs and bootstrap intervals. |
| - `figures/`: vector PDF and 600-dpi PNG manuscript figures. |
| - `manifests/`: provenance, checksums, split definitions, and processing logs. |
| - `code/`: exact Colab notebook and support package. |
|
|
| ## Important limitations |
|
|
| SMAP is treated as an external reference product rather than error-free ground |
| truth. The strict primary protocol uses the earliest 5% of 2025 observations as |
| chronological anchors and evaluates all later observations without anchor/test |
| overlap. |
